To aZZ whom it may concern:

lie it known that 1, JOHN V. HoLsTEIN, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Two-Row Gultivators, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to cultivators and more particularly to that type of cultivators employed for treating the soil between rows ot' growing vegetation.

The objects of my invention are to simplify and improve the adjustable features of machines of this class so that any adjustment desired to facilitate proper cultivation can be quickly and easily secured. Other objects will be disclosed in the following specification:

Referring to the drawings in which similar numerals indicate identical parts- Figure 1 is a plan view of my improved cultivator.

Fig. 2 is a front elevation.

Fig. 3 is a detail section on the line 3-3 of Fig. 1. i

Fig. i is a rear elevation of one end of the cultivator.

Fig. 5 is an enlarged View of part of the adjusting mechanism.

Fig. 6 is an enlarged detail side elevation of part of the adjusting mechanism.

Fig. 7 is an enlarged detail of lever mountings.

Fig. 8 is an enlarged detail sectionof part of the wheel control mechanism.

Fig. 9 is an enlarged detail of a rear. arch connection to the tool beams.

Fig. 10 is an enlarged detail of a rear arch connection with the frame. I i

Fig. 11 is an enlarged detail of a connection of a lifting link and spring with a tool beam.

Fig. 12 is an enlarged detail of an end of a front arch showing brace connections. The main frame comprises a front bar 1 and a rear bar 2 spaced apart and rigidly connected by end bars 3;.cr0ss bars 4, 5, 6 and 7 at suitable intervals extend between the bars 1 and 2 and are rigidly secured thereto. Brackets 8 are secured to the ends of the bar 2 and have vertical tubular bearrigidly secured forwardly extending arms 14;. Secured on the bars 5 and 6 are standards 15 having slots or guideways 16 in which is slidably supported a bar 17, the latter having perforations at its extremities in. which are secured in any suitable manner the ends of rods 18 which extend to the arms 14 and have a threaded engagement with members 19 which are pivotally supported on the arms 14c by means of studs 20, preferably integral with the member 19, and which project through openings in the arms 14% and are secured therein by pins or cotters 21. Central of the underside of the sliding bar 17 and attached thereto is a lug 22 to which is connected, preferablyby its central link, a chain 23 which is practically divided by the lug 22 into two portions 24 and 25; the portion 24- passes over a roller 26, mounted on a support 27 in the bar 5, and extends downwardly to a foot lever -28, the latter being pivotally supported on a bracket 28 on the bar 1 and having a treadle 29 mount ed on its free end; the portion 25 of the chain 23 passes over a roller 30, mounted on a support 27 on the-bar 6, and extends downwardly to a foot lever 31 which is pivotally supported on the bracket 28 on the bar 1 and has a treadle 32 mounted on its I free end. Secured to the bars 5 and 6 are seat bars 33 which are further supported by brackets through which the seat bars 33 extend rearwardly, converging toward their rear ends and supporting thereon a seat 34:.

It will be noted that the seat 34 is so situated that the treadles 29 and 32 are within easy reach. The operative mechanism just described relates to adjustment of the wheels 10 so that the cultivator can be guided while in operation to prevent injury to the plant row and to insure proper stirring of the soil adjacent thereto, for it is obvious that pressure upon the treadle 011 the lever on the side to which it is desired the machine should move will rock that lever downwardly pulling down the portion of the chain 23 connected to it and the lug 22, this action will operate the bar 17 to slide in the guideadjusted in a similar manner a description of one will suflice. Each group consists in this instance of two beams 35 having their forward ends loosely mounted to permit of a vertical rocking movement on horizontal end portions 36 of an arch 37; the arch 37 is laterally movable, as will be hereinafter explained, and is supported by rods 38 hav ing their upper ends bent to engage with eyes 39 mounted on the frame bar 2; the

lower ends of the rods 38 are bent to hook into eyes on collars 40 mounted on the horizontal portions 36 of the arch 37; similar eyes are formed on the forward side of the collars 40 for the reception of hook ends of rods 41 which extendtoward the frame bar 1 and have their ends bent to engage with a suitable perforation in said bar. I have shown cultivator shovels carried by the beams 35, but it is obvious that other earth stirring devices can be substituted therefor. 1

Connected to the forward part of the beams 35 rearward of the connection of the latter to the arch 37 are coiled springs 42 the upper ends of which engage with eyes in bolts 43 rigidly attached to the rods 38 by clips 44. On the rear of the frame bar 2 is a rod 45 slidably mounted inbrackets 46 secured to the frame bar 2; clamps 47 are rigidly secured on the rod 45 and have slots 48 below the rod 45. -Aspreader arch 48 composed of two members 49 and 50, each member having a vertical portion a and a horizontal portion 5, is supported by the clamps 47 by passing the portions 5 through the slots 48, one overlapping the other, and tightening the clamps by bolts 0, the bottom of the clamps 47 being split for the purpose. The lower ends of the vertical portions (0 project loosely through slots in clips 52 rigidly secured on the beams 35. By the use of an arch of this description the beams 35 of each group can be'adjusted toward or from each other by loosening the bolts 0 in the clamps47 and moving the arch members;

49 and 50 until the desired width between the beams 35 has been obtained when the bolts are again tightened to hold the arch members 49 and 50 in their adjusted position; when this adjustment is made the widths betweenrows of plants.

beams 35 will be diiawn closer together or' farther separated the vertical arch portions ato adapt the cultivator for varying As the beams 35 are moved; by adjustment of the arch portions a and b, the forward ends of the beams 35, being loosely mounted on the horizontal portions of the arch 37 can be moved laterally, agreeable with the movement of the beams by adjustment of the spreader arch, when the set screws 40, which hold the collars 40 to the horizontal portions of the arches 37, are loosened.

Bigidly secured on the standards 15, and preferably in the same plane and parallel with the bar 17, is a bar 53 having perforations d in each end; in order to relieve the driver of the necessity of holding the wheels 10 against swin /ing particularly when the machine is being moved from place to place, the rods 18 cal? be disconnected from the bar 17 and thei ends secured in the perforations d, of the bar 53, and as the latter is immovable tlte wheels are held securely against swinging.

.To raise or lower the beams 35 individually, or collectively we employ the following mechanism; secured on the frame bar 2 are bearings e, f, g, and it; supported in the bearings, f and g are the ends of a bar 54 which is preferably square. Both ends of the bar 54 are bored to admit the reduced ends of bars 55 and to form bearings thereforythe bars 55 rock in the bearings e and h, and have that part of their length outside of the bearings e and h bent at a right angle to form arms j extending toward the inside the bearings e and it against which they contact .to prevent longitudinal move- 7 ment of the bars 55. The free ends of the arms j are perforated for engagement of the hook ends of links 57 which extend downwardly through members 58 secured on the outer beams 35, and are secured against withdrawal therefrom by cotters in the ends of said links and below the members 58; coiled springs 59 on the links 57 exert their pressure between the members 58 and pins 30 on the links 57 The ends of the bar 54 project beyond the bearings f and g and have mounted rigidly upon them double sectors 61; on the inner ends of the bars 55 are rigidly secured hand levers 62 provided with the usual form of latch to engage with notches on the adjacent side of the sectors 61; similar levers 62 are loosely mounted on the ends of the bar 54, and have similar latches to engage with notches in the adjacent side of the sectors 61. The levers 62 are provided with arms is, similar to the arms j, and to which are connected links 63 which extend downwardly-through members 64 on ill lid

t ste the inner beams the links 63 have coiled springs which exert their pressure between the members (it and pins on the linlrs (53, the latter being held against withdrawal from the members ill by pins or cotters in the ends of the links below the members (it. A master lever (36 is rigidly mounted on the bar 54 and is provided with a common form of latching device to engage with notches in a segment (J secured to the frame bars 2 and ii.

The le er mechanism just described is for the purpose of raising and lowering the beams 35 individually by operation of the lever 62 (omiected therewith through the links 51' and ($3, the desired position of the beams 35 when raised or lowered being lined by the latches on the levers i352 engaging with notches in the sectors (51; as previously stated the sectors 61 and the master lever 66 are rigidly mounted on the bar at, it will therefore be apparent that when the levers (52 are held by engagement of their latches with the sectors 61, the beams can be raised simultaneously by operation of the master lever 66 and held in a raised position by the latch on the lever 66 engaging with a notch in the segment 37.

it segment 68, substantially horizontal is provided with forwardly extending parallel arms 69 and 70 connected by an arched rib T1 and which is preferably integral therewith; the arms 69 and 70, have Slots 72 therein to admit the bars 17 and which support the segment 68 and on which the latter is adapted to lateral movement, the slots 72 being sufliciently large for that purpose. Pivotally supported intermediate its length on the underside of the arched rib T1 is a hand lever 73 whi h is'provided with the usual form of latch to engage with the notches in the segment 08; the lever 73 has pivotally connected to its forward end a rod it which is extended late ally and connected to an arm 75 rigidly secured on one of the arches 37. Pivoted intermediate its length on the upper side of the rib T1 is a hand lever 76 having a latch to engage with notches in a segment 7? similar to the segment SH and parallel therewith; the segment IT is secured to the arms 69 and '10 by bolts or rivets 0. ll rod 78 is pivotally con nected to the forward end of the lever 76 and extends in the opposite direction from the rod l t and is connected to an arm 79 rigidly mounted on the other arch 37. By operating the levers T3 and "(ii the two groups of beams connected to arches 3? and alt? are adjusted toward or from each other: the arches I'll" swinging on the supporting rods 38 and their tops moving in forked guides 37 rigidly secured to the bars n T.

secured to the sliding bar 17 by pins or cotters 17 inserted in perforations 1n the arms (39 and 70 and the sliding bar 17, and the levers 7 3 and 76 are locked to the segments (38 and 77, so that if the foot levers 28 and 31 are operated to swing the wheels ll) the arches 37 and 4E8 will be simultaneously moved in the same direction yet it will still be possible to adjust either group of beams independently by operation of the levers T3 and 76. if it is desired however to separate the adjustment of the wheels and the groups of beams 35, the cotters 17 are withdrawn from the arms 69 and 70 and the sliding bar 17 and inserted in perforations 80 in the forward ends of the arms 69 and T0, and through similar perforations in the bar 53, so that the wheels can be swung without affooting the position of the groups of beams 35, the latter still being capable of lateral adjustment by operating the levers 78 and 76; when the rods 18 are disconnected from the sliding bar 17 and connected to the bar the wheels are held against adjustment by operation of the foot levers 28 and 31, and

if the arms 69 and 70 are also secured to the bar 53 it is evident that the groups of beams only are capable of adjustment.

The coiled springs 42, as shown and de scribed, are connected to the forward parts of the beams 35 rearward of the pivotal connections of the latter to the arches 37, and are also connected to the 11 )per portions of the rods 38 instead of to t e frame as has been customary heretofore; by attaching the springs 42 to the upper portions of the rods 38, the tension of the springs 42 in balancing the beams 35 is not increased when the arches 37 are moved laterally, the rods 38 swinging laterally with them and carrying the springs 42 so that the relative position of the latter to the beams 35 and the rods 38 remain unchanged during the lateral movement of the arches and beams.

From the foregoing description it will be apparent that my improved cultivator is capable of a wide range of adjustment to suit any condition of crops grown in rows.
